Quality Control

Screen Stretcher Control
Screen Stretcher Control
Screen Stretcher Control

1. Tension detection: use a tensiometer to ensure that the screen tension is stable (usually 20-25N/cm²) 2. Exposure accuracy: UV exposure time calibration to avoid pattern edge jaggedness 3. Stencil cleanliness: check for clogged stencils in a dust-free environment (microscope assisted)

Print Positioning System
Print Positioning System
Print Positioning System

1.CCD visual alignment: ±0.1mm error range of automatic calibration 2.Fixture precision: Vacuum adsorption platform flatness ≤ 0.05mm. 3.Multi-color overprinting: Verify the position offset of each color plate by laser sensor.

Ink Control
Ink Control
Ink Control

1. Viscosity monitoring: dynamic adjustment of ink viscosity (e.g. 25±2 seconds/coating 4 cups) 2. Thickness detection: online thickness gauge to control the thickness of the ink layer (±5μm) 3. Color management: Pantone color card comparison, color difference ΔE ≤ 1.5

Scraper parameters

Scraper parameters

1. Angle/Pressure: Squeegee angle 60±5°, pressure 0.2-0.4MPa (adjusted according to material) 2. Wear monitoring: check the flatness of the blade every 5000 prints. 3. Ink return knife synchronization: to ensure that the ink evenly covers the mesh.

Drying and Curing

Drying and Curing

1. IR/U curing: temperature profile monitoring (e.g. UV energy 800-1200mJ/cm²) 2.Adhesion test: Hundred grid knife scratch method (ISO grade ≥ 4B) 3.Volatile matter test: VOC residue ≤ 100ppm

Finished Product Inspection

Finished Product Inspection

1. Automatic AOI Inspection: Identify missing ink/overflow/overprint deviation (60-120 times per minute) 2.Dimension measurement: projector verification of pattern position tolerance (±0.3mm) 3.Abrasion test: test with RCA paper tape machine (≥300 times friction)

Environment & Maintenance

Environment & Maintenance

1. Workshop temperature and humidity: keep 25±2℃, 50±5%RH 2. Equipment calibration cycle: check rail/belt tension weekly 3.Data traceability: MES system records each batch of process parameters
